kintai wo kakuninsimasu.

It is read:

きんたい を かくにんします。

• 勤怠 = きんたい
• を = o (the particle is written を but pronounced お in modern Japanese)
• 確認します = かくにんします

So the full sentence is:

きんたいをかくにんします。

勤怠 is a workplace/business term. It refers to a person’s attendance and work-status record, such as:

• being present or absent
• lateness
• early departure
• working hours
• leave status

So it is not just simple school-style attendance. It is more like attendance/work-time status in a company or organization.

を marks the direct object of the verb.

In this sentence:

• 勤怠 = the thing being checked
• 確認します = check / confirm

So を shows that 勤怠 is what is being confirmed.

A simple structure is:

[object] を [verb]

So here:

勤怠を確認します。
= (I / we / someone) check(s) attendance/work-status records.

確認します comes from the noun 確認 plus する, which makes it a suru-verb.

• 確認 = confirmation / checking
• 確認する = to confirm / to check
• 確認します = polite form of 確認する

This pattern is very common in Japanese, especially in formal or business language.

Examples:

• 連絡します = I will contact / I contact
• 説明します = I will explain / I explain
• 確認します = I will confirm / I confirm

So 確認します is a very normal and natural verb form.

The ます form is the polite form. It is commonly used in:

• workplaces
• customer service
• announcements
• formal conversations
• written instructions in professional settings

Since 勤怠 is itself a business-related word, 確認します sounds very natural.

The plain form would be:

勤怠を確認する。

That version may sound:

• more dictionary-like
• less polite
• more like a note, heading, or casual statement

Japanese often omits the subject when it is clear from context.

So 勤怠を確認します。 does not explicitly say who is doing the checking. Depending on the situation, it could mean:

• I will check attendance
• We check attendance
• Please check attendance (in some instruction-like contexts, though a more direct request form is also possible)
• The system/person in charge checks attendance

Japanese usually leaves this unstated if the listener can figure it out from the situation.

Not really in casual daily conversation. It is mainly used in:

• companies
• HR
• payroll
• internal office communication
• work management systems

A native speaker would strongly associate 勤怠 with the workplace.

In everyday casual speech, people are more likely to talk more specifically about things like:

• 出勤 = going to work / clocking in
• 退勤 = leaving work / clocking out
• 遅刻 = being late
• 休み = day off / absence

So 勤怠 sounds fairly formal and administrative.

Yes, you can, and it may sound natural in some workplaces. However, there is a nuance difference:

• 確認します = more formal, standard, businesslike
• チェックします = a bit more casual, lighter, sometimes more conversational

In official business Japanese, 確認します often sounds better and more professional.

So:

• 勤怠を確認します。 = very standard in formal/business settings
• 勤怠をチェックします。 = also possible, but less formal

Normally, no.

確認する usually takes the thing being confirmed as a direct object, so を is the natural particle:

• 勤怠を確認します。

Using が here would not be the normal pattern for this sentence.

As a beginner-friendly rule:

• use を for the thing you directly do the action to
• use が for the subject, or in some special verb patterns

Since you are checking the attendance record, 勤怠 is the object, so を is correct.

Yes. It is short, natural, and common in business contexts.

It could appear in situations like:

• a manager speaking
• an office procedure manual
• a workflow description
• a system message or task list
• an employee explaining what they are doing

Because Japanese often omits the subject, a short sentence like this is completely normal if the context is already understood.

Both can relate to looking, but they are not the same.

• 見ます = look at / see
• 確認します = confirm / check carefully / verify

So 確認します suggests more than just visually looking. It implies making sure the information is correct or reviewing it properly.

For workplace records like 勤怠, 確認します is much more natural than 見ます.

• 勤怠を見ます。 = I look at the attendance record
• 勤怠を確認します。 = I check/confirm the attendance record

The second one sounds more purposeful and professional.
